When I read about these schemes to produce gasoline from CO2 and water or whatever I can't help but think someone needs a couple of semesters of thermodynamics beat into them.
No more than 20% if that. That translates into synth gasoline at $30/gallon
This wont be able to decarbonize anything until surplus carbon free energy is generated for it use - that need not take decades with proper governmental policies, but it means this technology will not lead the way.
